Possibly it's not ssh that closes the connection. Are there any routers 
between your machine and the remote one? If this is the case it could be 
one of the routers that has a low timeout for recognizing a connection 
as "alive". This happens especially if NAT is used, because the router 
has to keep a table of ip:port pairs for each connection. This should 
happen only if there is no traffic on the connection within this timeout 
limit.
